The velocity vectors of the bubbles are measured by a stereoscopic bubble-tracking technique and then the relative velocity vectors of two nearest neighbor bubbles are calculated with high statistical reliability. With the measurement data at Reynolds number ranging from ,5 to 7,5, the vertical attraction and the horizontal repulsion are confirmed for Re<10 as known by the past study based on Navier Stokes simulation. The new finding of the present measurement is that the bubbles of Re >30 have repulsive velocity bothin the horizontal and the vertical directions as those rise closely. Moreover, the three-dimensional structure of the bubble-bubble interaction is discussed with the data analysis of the interaction vector fields.
